BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a vaporization device and a method thereof, and more particularly to an electronic device providing an inhalable aerosol and a method thereof.

2. Description of the Related Art

An electronic cigarette is an electronic product that heats a vaporizable solution and vaporizes the solution to produce an aerosol for a user to smoke.

In recent years, major manufacturers begin to produce various electronic cigarette products. Generally, an electronic cigarette product includes a housing, an e-liquid storage chamber, an vaporization chamber, a heating component, an air inlet, an airflow channel, an air outlet, a power supply device, a sensing device and a control device. The e-liquid storage chamber is configured to store a vaporizable solution, and the heating component is used to heat and vaporize the solution to generate an aerosol. The air inlet is in communication with the vaporization chamber, and provides air to the heating component when the user inhales. The aerosol generated by the heating component is first generated in the vaporization chamber, and subsequently inhaled by the user via the airflow channel and the air outlet. The power supply device supplies power needed by the heating component, and the control device controls the heating time of the heating component according to an inhalation action of the user detected by the sensing device. The housing wraps all the foregoing components.

Existing electronic cigarette products have different defects, which may result from poor designs of relative positions between different members. For example, common electronic cigarette products are designed to align the heating component, the airflow channel and the air outlet in a vertical direction. Since the airflow has a specific length, the aerosol is cooled when passing through the airflow channel, and a condensed liquid is formed on the airflow channel wall. Under this design, when the condensed liquid reaches a specific volume, the user is likely to inhale the condensed liquid directly and consequently have a bad experience of choking.

In addition, existing electronic cigarette products are not designed to avoid countercurrent flow of condensate. When the electronic cigarette is tilted or placed upside down, the condensed liquid remaining in the vaporization chamber and the airflow channel may leak from the air inlet or the air outlet. The leaking condensed liquid may damage electrical components (for example, the sensing device and the control device) in the electronic cigarette product.

Further, existing electronic cigarette products are not designed to control the power output of the heating component. When the user inhales for a long time, the power supply device continuously heats the heating component, and the heating component may be overheated and produce a burnt smell, causing a bad experience for the user. The overheated heating component may also destroy or burn the internal components of the electronic cigarette. Fast power consumption is also a general disadvantage of existing electronic cigarette products that are not designed to control the output power.

Therefore, a vaporization device and a method thereof are provided to resolve the foregoing problems.

FIG. 3A and FIG. 3B are sectional views of a cartridge according to some embodiments of the present invention.

As shown in FIG. 3A, the cartridge housing 3 includes an e-liquid storage compartment 30, an air inlet channel 31 and an air outlet channel 32.

In some embodiments, the air inlet channel 31 and the air outlet channel 32 may be located inside the cartridge housing 3. In some embodiments, the air inlet channel 31 and the air outlet channel 32 may be defmed by an internal structure of the cartridge housing 3. In some embodiments, the air inlet channel 31 and the air outlet channel 32 may be defmed by the cartridge housing 3 and the body housing 24 together. In some embodiments, the air inlet channel 31 may be defined by the internal structure of the housing 3 and the heating component base 8 together. In some embodiments, the air outlet channel 32 may be defined by the internal structure of the housing 3 and the heating component base 8 together.

The air inlet channel 31 is located on one side of the cartridge housing 3, and the air outlet channel 32 is located on the other side of the cartridge housing 3. In some embodiments, the air inlet channel 31 may be located on one side of the heating component 6, and the air outlet channel 32 may be located on the other side of the heating component 6 opposite to the air inlet channel 31.

In some embodiments, the pipe diameter of the air inlet channel 31 may be the same as that of the air outlet channel 32. In some embodiments, the pipe diameter of the air inlet channel 31 may be different from that of the air outlet channel 32. In some embodiments, the pipe diameter of the air inlet channel 31 may be smaller than that of the air outlet channel 32. Smaller pipe diameter of the air inlet channel 31 may make it easier for the sensor starter tube 7 to generate a negative pressure. Smaller pipe diameter of the air inlet channel 31 may make it easier for the sensor 16 to detect an inhalation action of the user.

In some embodiments, the air inlet channel 31 and the air outlet channel 32 may be configured asymmetrically in the cartridge housing 3.

As shown in FIG. 3A, the vaporization chamber 8 c may be a cavity between the heating component 6 and the heating component base 8. As shown in FIG. 3A, the vaporization chamber 8 c may be defined by the heating component 6 and the heating component base 8 together. The air inlet channel 31 is in communication with the vaporization chamber 8 c. The air outlet channel 32 is in communication with the vaporization chamber 8 c. The part where the air inlet channel 31 is in communication with the vaporization chamber 8 c is located below the heating component 6. The part where the air outlet channel 32 is in communication with the vaporization chamber 8 c is located below the heating component 6. The foregoing configuration has many advantages. The configuration can at least partially vent the airflow away from the heating component 6. The configuration can at least partially prevent the airflow from flowing directly through the heating component 6. Compared to the prior art where the airflow needs to pass directly through the heating component, the effect of a material of the heating component on the flavor of e-liquid (vaporizable material) is reduced. In addition, when the user vertically holds the vaporization device 100, the condensed liquid remaining on the inner wall of the air inlet channel dose not drip on the heating component 6 even if it flows backwards, so that the condensed liquid can be prevented from clogging the heating component 6.

As shown in FIG. 3A, the sensor starter tube 7 is disposed on the heating component base 8. The length of the sensor starter tube 7 that protrudes from the heating component base 8 is 7L. The part of the sensor starter tube 7 protruding from the heating component base 8 can be disposed in the air inlet channel 31. When the vaporization device 100 is being used, an aerosol may condense into a liquid 32 d and remain on an inner wall of the air outlet channel 32. The liquid 32 d may flow back and accumulate in an e-liquid tank 8 t (refer to FIG. 8A to FIG. 8D). In some circumstances, the vaporizable material stored in the e-liquid storage compartment 30 may also leak into the e-liquid tank 8 t through the bottom of the heating component 6. The part of the sensor starter tube 7 exceeding the heating component base 8 can present the liquid stored in the e-liquid tank 8 t from leaking through the through hole 8 h 2.

In some embodiments, the length 7L is within a range of 1 mm to 10 mm. In some embodiments, the length 7L is within a range of 1 mm to 6 mm. In some embodiments, the length 7L is within a range of 1 mm to 4 mm. In some embodiments, the length 7L is within a range of 1 mm to 2 mm. In some embodiments, the length 7L may be 1.5 mm. In some embodiments, the length 7L may be 2 mm.

In some embodiments, the sensor starter tube 7 and the heating component base 8 may be two separate components. In some embodiments, the sensor starter tube 7 and the heating component base 8 may be formed integrally. In some embodiments, the sensor starter tube 7 may be made of a metal material. In some embodiments, the sensor starter tube 7 may be made of a plastic material. In some embodiments, the sensor starter tube 7 and the heating component base 8 may be made of a same material. In some embodiments, the sensor starter tube 7 and the heating component base 8 may be made of different materials.

As shown in FIG. 3B, the length of the air inlet channel 31 is 31L, and the length of the air outlet channel 32 is 32L. In some embodiments, the length 31L may be different from the length 32L. In some embodiments, the length 31L may be less than the length 32L.

The length 7L and the length 31L may be in a proportional relationship. In some embodiments, a proportion of the length 31L and the length 7L may be within a range of 6 to 7. In some embodiments, a proportion of the length 31L and the length 7L may be within a range of 7 to 8. In some embodiments, a proportion of the length 31L and the length 7L may be within a range of 8 to 9. In some embodiments, a proportion of the length 31L and the length 7L may be within a range of 9 to 10.

The air inlet channel 31 is in communication with the external through a through hole 31 h on the cartridge housing 3. The air outlet channel 32 is in communication with the outside through a through hole 1 h on the mouthpiece 1. In some embodiments, the through hole 31 h and the through hole 1 h are located in different positions in the horizontal direction. In some embodiments, the distance between the through hole 31 h and the heating component 6 is different from the distance between the through hole 1 h and the heating component 6. In some embodiments, the distance between the through hole 31 h and the heating component 6 is less than the distance between the through hole 1 h and the heating component 6.

The e-liquid storage compaitinent 30 is a sealed area. The e-liquid storage compailinent 30 may be formed by compartment structures 30 w 1 and 30 w 2 in the cartridge housing 3 and the heating component top cap 4. A part where the heating component top cap 4 makes contact with the compailinent structures 30 w 1 and 30 w 2 has a sealing member 4 r. The sealing member 4 r makes the heating component top cap 4 and the compailinent structures 30 w 1 and 30 w 2 closely in contact with each other.

The sealing member 4 r may prevent the vaporizable material stored in the e-liquid storage compartment 30 from leaking out.

In some embodiments, the heating component top cap 4 and the sealing member 4 r may be formed by using a same process. In some embodiments, the heating component top cap 4 and the sealing member 4 r may be formed by using a same process and different materials. In some embodiments, the heating component top cap 4 and the sealing member 4 r may be formed by injection molding. In some embodiments, the heating component top cap 4 may be produced by injection molding using a plastic material. In some embodiments, the sealing member 4 r may be produced by injection molding using liquid silica on the heating component top cap 4.

In some embodiments, the heating component top cap 4 and the sealing member 4 r may be formed by using different processes and subsequently combined with each other. In some embodiments, the heating component top cap 4 is produced by injection molding using a plastic material, and the sealing member 4 r is produced by compression molding. The heating component top cap 4 and the sealing member 4 r are combined with each other by using an additional component step.

When the user inhales, air enters from a gap between the cartridge 100A and the body housing 24, and experiences the direction change 3 f 1 between the cartridge 100A and the body housing 24. Subsequently, the air enters the air inlet channel 31 through the through hole 31 h, and experiences the direction change 3 f 2 before entering the vaporization chamber 8 c.

An airflow 7 f is generated in the sensor starter tube 7 by the inhalation action of the user. The airflow 7 f enters the cartridge 100A from the sensor starter tube 7. In some embodiments, the airflow 7 f may enter the air inlet channel 31. In some embodiments, the airflow 7 f may enter the vaporization chamber 8 c with the inhalation action of the user. In some embodiments, part of the airflow 7 f may enter the air outlet channel 32 with the inhalation action of the user.

The airflow 7 f is detected by the sensor 16 when passing through a gap between the cartridge 100A and the body 100B. The controller 171 activates the heating component 6 based on a detection result of the sensor 16, and generates an aerosol in the vaporization chamber 8 c. The generated aerosol experiences the direction change 3 f 3 when the aerosol just enters the air outlet channel 32. The generated aerosol subsequently experiences the another direction change 3 f 4 at the through hole 1 h in the air outlet channel 32 close to the mouthpiece 1. The generated aerosol experiences the another direction change 3 f 5 when leaving the through hole 1 h on the mouthpiece 1.

When the vaporization device 100 is being used, the aerosol may condense into a liquid 32 d and remain on an inner wall of the air outlet channel 32. The condensed liquid 32 d is viscous and does not easily flow on the inner wall of the air outlet channel 32. When the user is inhaling, the plurality of direction changes 3 f 3, 3 f 4 and 3 f 5 included in the air outlet channel 32 may preferably prevent the condensed liquid 32 d from being inhaled by the user through the through hole 1 h.

The airflow has a temperature rise Tr after passing through the vaporization chamber 8 c from the air inlet channel 31. In some embodiments, the temperature rise Tr may be within a range of 200° C. to 220° C. In some embodiments, the temperature rise Tr may be within a range of 240° C. to 260° C. In some embodiments, the temperature rise Tr may be within a range of 260° C. to 280° C. In some embodiments, the temperature rise Tr may be within a range of 280° C. to 300° C. In some embodiments, the temperature rise Tr may be within a range of 300° C. to 320° C. In some embodiments, the temperature rise Tr may be within a range of 200° C. to 320° C.

An airflow from the vaporization chamber 8 c may has a temperature drop Tf before reaching the through hole 1 h. The airflow from the vaporization chamber 8 c may has a temperature drop Tf when passing through the air outlet channel 32. In some embodiments, the temperature drop Tf may be within a range of 145° C. to 165° C. In some embodiments, the temperature drop Tf may be within a range of 165° C. to 185° C. In some embodiments, the temperature drop Tf may be within a range of 205° C. to 225° C. In some embodiments, the temperature drop Tf may be within a range of 225° C. to 245° C. In some embodiments, the temperature drop Tf may be within a range of 245° C. to 265° C. In some embodiments, the temperature drop Tf may be within a range of 145° C. to 265° C.

In some embodiments, the aerosol inhaled by the user via the through hole 1 h can have a temperature below 65° C. In some embodiments, the aerosol inhaled by the user via the through hole 1 h can have a temperature below 55° C. In some embodiments, the aerosol inhaled by the user via the through hole 1 h can have a temperature below 50° C. In some embodiments, the aerosol inhaled by the user via the through hole 1 h can have a temperature below 45° C. In some embodiments, the aerosol inhaled by the user via the through hole 1 h can have a temperature below 40° C.

FIG. 5A and FIG. 5B are sectional views of a cartridge according to some embodiments of the present invention.

As shown in FIG. 5A, a blocking component 33 a may be disposed in the air inlet channel 31. The blocking component 33 a may have a through hole 33 h. A diameter of the through hole 33 h is smaller than the pipe diameter of the air inlet channel 31. The through hole 33 h may be regarded as a portion of the air inlet channel 31. The thickness of the blocking component 33 a is 33L. The thickness 33L of the block component 33 a results in a height drop in the air inlet channel 31. Since the liquid or the e-liquid stored in the e-liquid tank 8 t is viscous, the height drop facilitates preventing the liquid or the e-liquid stored in the e-liquid tank 8 t from flowing backwards. The height drop facilitates preventing the liquid or the e-liquid stored in the e-liquid tank 8 t from leaking via the through hole 31 h.

In some embodiments, the block component 33 a may be made of silica gel. In some embodiments, the block component 33 a may be a silicone ring. In some embodiments, the block component 33 a and the housing 3 may be made of a same material. In some embodiments, the block component 33 a and the housing 3 may be made of different materials. In some embodiments, the block component 33 a and the housing 3 may be two separate components. In some embodiments, the block components 33 a and the housing 3 may be formed integrally.

As shown in FIG. 5B, a blocking component 33 b may be disposed in the air inlet channel 31. The blocking component 33 b may cause the air to enter the air inlet channel 31 through the through hole 31 h. The block component 33 b may prevent the liquid from flowing from the e-liquid tank 8 t to the through hole 31 h. In some embodiments, the block component 33 b may be a check valve.

A blocking component 34 may be disposed in the air outlet channel 32. The blocking component 34 may have one or more through holes 34 h. The blocking component 34 may cause the aerosol to flow from the vaporization chamber 8 c to the through hole 1 h. Since the liquid or e-liquid stored in the e-liquid tank 8 t is viscous, the hole diameter of the through hole 34 h is designed to prevent the liquid or the e-liquid from flowing from the e-liquid tank 8 t to the through hole 1 h.

FIG. 6A, FIG. 6B, FIG. 6C, FIG. 6D and FIG. 6E are top views of a heating component top cap according to some embodiments of the present invention.

The e-liquid stored in the e-liquid storage compailinent 30 may make contact with the heating component 6 through a through hole 4 h on the heating component top cap 401 and a through hole 5 h on the silicone heating component seal member 5.

The hold diameter and shape of the through hole 4 h may be adjusted according to the property of the e-liquid. In some embodiments, if the viscosity of the e-liquid is relatively high, the hole diameter of the through hole 4 h can be designed relatively big. In some embodiments, if the viscosity of the e-liquid is relatively low, the hole diameter of the through hole 4 h can be designed relatively small. The through hole 4 h with a relatively small hole diameter may prevent excessive e-liquid from making direct contact with the heating component 6. The through hole 4 h with a relatively big hole diameter may ensure more e-liquid to make direct contact with the heating component 6.

The hole diameter of the through hole 4 h may be appropriately adjusted according to the property of the e-liquid, so that the heating component 6 can make contact with enough e-liquid to avoid dry burning during heating and prevent the generated aerosol from having a burnt odor.

The hole diameter of the through hole 4 h may be appropriately adjusted according to the property of the e-liquid to prevent the heating component 6 from making contact with excessive e-liquid. The excessive e-liquid cannot be adsorbed by the heating component 6, and gradually permeates from the e-liquid storage compailinent 30 to the e-liquid tank 8 t through the heating component 6. If the amount of e-liquid permeating into the e-liquid tank 8 t is excessively large, the probability of the e-liquid flowing into the air inlet channel 31 and the air outlet channel 32 will increase. If the amount of e-liquid permeating into the e-liquid tank 8 t is excessively large, the probability of the e-liquid permeating out of the through hole 31 h of the air inlet channel and the through hole 32 h of the air outlet channel will increase.

FIG. 10 is a flowchart of an output power control method according to some embodiments of the present invention.

The output power control method 200 may include a plurality of steps. In some embodiments, the steps in the output power control method 200 may be performed sequentially in the order shown in FIG. 10. In some embodiments, the steps in the output power control method 200 may not be performed in the order shown in FIG. 10.

Step 201: Detect an inhalation action of the user. The Step 201 may be performed by a sensor 16 and a controller 171 in combination.

Step 202: Determine whether a duration in which a power outputted to the heating component 6 is stopped is greater than a threshold TN1. If the time when an output power to the heating component 6 is stopped is greater than or equal to the threshold TN1, Step 203 is performed. If the time when an output power to the heating component 6 is stopped is less than the threshold TN1, Step 204 is performed. Step 202 may be performed by setting a timer in the controller 171. A timer may be set in the controller 171, and starts when the power supply component 20 stops provide power for the heating component 6.

In some embodiments, the threshold TN1 is within a range of 15 seconds to 60 seconds. In some embodiments, the threshold TN1 is within a range of 25 seconds to 40 seconds. In some embodiments, the threshold TN1 may be 30 seconds.

Step 203: Output a power P1 to the heating component 6 in a duration S1, and output a power P2 to the heating component 6 in a duration S2 after the duration S1. The duration S1 and the duration S2 are both during the continuous inhalation action of the user. Step 204 may be performed by the controller 171, a circuit board 17, a power supply component 20, a conductive contact 9, a conductive probe 15 and the heating component 6 in combination.

In some embodiments, the power P1 may be greater than the power P2. In some embodiments, P1 is within a range of 6 W to 15 W. In some embodiments, P1 is within a range of 7.2 W to 9 W. In some embodiments, P2 is within a range of 4.5 W to 9 W. In some embodiments, P2 is within a range of 6 W to 8 W.

In some embodiments, S1 is within a range of 0.1 second to 2 seconds. In some embodiments, S1 is within a range of 0.1 second to 1 seconds. In some embodiments, S1 is within a range of 0.1 second to 0.6 seconds.

In some embodiments, S2 is within a range of 0.1 second to 4 seconds. In some embodiments, S2 is within a range of 0.1 second to 3.5 seconds.

Step 202 and Step 203 have a plurality of advantages. Whether the vaporization device 100 has not been in use for a long time can be determined by the threshold TN1. The heating component 6 appears in a cool state when the user has not used the vaporization device 100 for a long time. When the user performs a first inhalation action to the vaporization device 100, the vaporization device 100 may output a relative high power P1 in the duration S1. The relative high power P1 may accelerate the generation of an aerosol. When the inhalation action of the user lasts for the duration S2, the heating component 6 already has a specific temperature, and the vaporization device 100 can reduce the output power to P2. The reduced power P2 may allow the aerosol to be generated uniformly. The reduced power P2 may increase the use time of the power supply component 20.

Step 204: Output a power P3 to the heating component. Step 203 may be performed by the controller 171, the circuit board 17, the power supply component 20, the conductive contact 9, the conductive probe 15 and the heating component 6 in combination.

In some embodiments, P3 is within a range of 3.5 W to 10 W. In some embodiments, P3 is within a range of 4.5 W to 9 W. In some embodiments, P3 is within a range of 6 W to 8 W. In some embodiments, P3 and P2 may be the same. In some embodiments, P3 and P2 may be different.

Step 202 and Step 204 have a plurality of advantages. Whether the vaporization device 100 has been used by the user in a short time can be determined by the threshold TN1. If the vaporization device 100 has been used by the user in a short time, the heating component 6 has not been cooled completely. If the vaporization device 100 has been used by the user in a short time, the heating component 6 has a specific temperature. In this case, the vaporization device 100 may adjust the output power to P3. The adjusted power P3 allows the aerosol to be generated uniformly. The adjusted power P3 may increase the use time of the power supply component 20.

Step 205: Stop outputting the power to the heating component when the duration of outputting the power to the heating component has reached the threshold TN2. Step 205 may be performed by setting a timer in the controller 171.

Step 205 has many advantages. When the time of the heating component 6 being continuously heated has reached the threshold TN2, the stop of heating may prevent the heating component 6 from being overheated. Overheated heating component 6 may damage another component inside the vaporization device 100. Overheated heating component 6 may decrease service lives of components inside the vaporization device 100. When the time of the heating component 6 being continuously heated has reached the threshold TN2, the stop of heating may prevent the heating component 6 from dry burning. Drying burning the heating component 6 may produce a burnt odor. Drying burning the heating component 6 may produce toxic chemicals.

In some embodiments, the threshold TN2 is within a range of 2 seconds to 10 seconds.

Step 206: The vaporization device 100 is triggered to enter a standby state when a duration in which the inhalation action has not been detected reaches a threshold TN3. When staying in the standby state, the power consumption of the vaporization device 100 is reduced. When staying in the standby state, the sensor 16 remains in an active state. Step 206 may be performed by setting a timer in the controller 171.

When the user stops inhaling, the output power control method 200 may further include a step of stopping outputting power to the heating component 6. The step may be performed by the sensor 16 and the controller 171 in combination.
